Definitions
- the present invention relates to an axle according to the preamble of claim 1, a trailer and a method for compensating for a deceleration of a first wheel head.
- axles are known in which both wheel heads are verbun via an axle differential and a generator with a recuperation device.
- both wheel heads can be subjected to an equally large deceleration or an equally large deceleration torque.
- energy can be recovered temporarily, for example during braking, or also continuously. Since the same amount of deceleration is applied to both wheel heads, it is ensured that the driving dynamics of such a vehicle remains stable while driving straight ahead.
- a recuperation device connected on both sides is costly and requires a lot of installation space. Such a solution is also very heavy. If the recuperation device is connected to only one wheel head on one side, only a weak generator can be used, as otherwise driving dynamics problems can arise. This means that only a small amount of energy can be recovered.
- the present invention is therefore based on the object of providing an axle, a trailer or utility vehicle trailer and a method for compensating for a deceleration of a first wheel head of an axle due to recuperation, make available, the energy can be efficiently recovered by means of a recuperation device and can be achieved with low manufacturing costs and low weight.
- an axle in particular special for commercial vehicles, the axle having a first wheel head and a second wheel head, which are arranged or can be arranged opposite and rotatable on the axis, a recuperation device that is connected to the first Wheel head is connected or can be connected and is designed to recuperate rotational energy of the first wheel head, a braking device that is designed to decelerate the second wheel head and a control unit that is designed to provide information about a deceleration of the first wheel head, which from the recuperation results, and / or a deceleration of the second wheel head to determine and to control the braking device and / or the Rekuperationsvor direction so that the deceleration of the first wheel head and the delay of the second wheel head are coordinated, includes.
- the axle can be a one-piece or multi-part axle.
- the axis can extend continuously or in areas along an axis of rotation which corresponds to the axis of rotation of wheels provided on the axis.
- the first and the second wheel head can be rotatable about the axis of rotation, in particular on the axis arranged in a rotationally fixed manner on the utility vehicle or trailer.
- the axle can be formed in an operating state, for example on a utility vehicle or a trailer.
- the wheel heads can be separate components that can be provided on the axle.
- the wheel heads can form an axial end of the axle.
- the wheel heads can be wheel hubs or elements on each of which a rim can be arranged.
- the wheel head can also be referred to as a wheel end will.
- the recuperation device can be a regenerative brake that can be configured to convert kinetic energy into storable electrical energy and / or into another form of energy.
- the recuperation device can work without wear, like an electrodynamic brake, for example.
- the recuperation device can comprise an electrical machine that can operate as a generator during a recuperation process.
- the electrical machine can be a synchronous motor or an asynchronous motor.
- a braking effect can be generated by operating the electrical machine as an electrical generator.
- This braking effect can be applied in the form of a delay to the wheel head connected to the recuperation device.
- the Rekuperationsvor direction is connected to only one wheel head of the two wheel heads provided on an axle. Installation space can thus be saved, since a differential and a connection between the recuperation device and the other wheel head of the axle can be dispensed with.
- the electrical energy recovered from the kinetic energy is not converted into heat in the recuperation device, but either stored in an accumulator provided in the vehicle or fed directly to consumers.
- the braking device can be any device which is designed to brake or decelerate the wheel head independently of the other wheel head provided on the same axle.
- the Bremsvor direction can also be arranged on the first wheel head as long as the braking device can brake the second wheel head individually (ie independently of the first wheel head).
- the braking device can be part of a parking brake, for example.
- decelerating or braking can be understood to mean a negative acceleration which has the effect that a rotational speed of the respective wheel head is reduced.
- the control unit can include a comparator unit that can receive information (for example measurement data) and output actuation commands that are coordinated therewith can. The control unit can use the actuation commands to control other systems on the basis of the information obtained.
- control unit can have a data connection (wired or wireless) to the respective system.
- a control unit already installed in the vehicle can be used as the control unit.
- the control unit can be designed so that it can control the recuperation device and / or the braking device in such a way that delays that are applied to the first wheel head or the second wheel head either by the braking device or the recuperation device are coordinated with one another. Matched to one another can mean that a torque resulting from the applied delays corresponds to a previously determined or set value and / or direction.
- the resulting torque can occur when the first wheel head rotates faster than the second wheel head or vice versa.
- the wheel head that rotates faster can cover a greater distance than the wheel head that rotates more slowly, as is the case, for example, when a vehicle on which the axle is installed drives through a curve.
- the control unit can control the braking device and / or the recuperation device in such a way that one of the wheel heads rotates faster than the other in order to cause the axle to change its direction of travel, ie to be able to be steered.
- Such a control can support or facilitate cornering of a vehicle on which the axle is provided. Furthermore, maneuvering the vehicle can be facilitated by such a control.
- the control unit can control the recuperation device and / or the braking device in such a way that the decelerations of the first wheel end and the second wheel end are essentially the same.
- the delays of the first wheel end and the second wheel end can be compared with one another and it can be determined whether the difference between the two delays is below a predetermined value or not. This ensures that the vehicle on which the axle is installed has driving dynamics during a deceleration process remains stable, although the recuperation device is only verbun with a wheel head.
- a one-sided deceleration of the first wheel head due to a recuperation of rotational energy of the first wheel head by targeted interventions by the braking device on the second wheel head can essentially be compensated for, so that the driving dynamics of the vehicle while driving straight ahead is not adversely affected.
- the first wheel end and the second wheel end can therefore be decelerated independently of one another.
- the present invention achieves an optimal balance between energy recovery and freeing costs and space used, so that the overall efficiency of the vehicle on which the axle is installed can be improved.
- the control unit can detect state values of the axle and / or the vehicle and on this basis control the recuperation device and / or the braking device in such a way that the detected values (i.e. the information) are in a desired (i.e. in a, for example, preset) range lie.
- it is set, for example, so that the resulting torque is as low as possible, so that optimal driving stability is ensured when driving straight ahead.
- the information can preferably include the deceleration or deceleration values of the first wheel end and / or of the second wheel end and / or a torque generated on the basis of the delays.
- the generated torque can be a resultant torque that is generated due to a deceleration of at least one of the wheel heads in the axle.
- the information can be data that can be fed to the control unit by at least one detection device.
- the resulting torque can result from the delay of the first wheel end and the delay of the second wheel end.
- the information can be obtained by sensors specially provided for this purpose, such as a speed sensor and / or an acceleration sensor, for example, or obtained via a system provided in the vehicle.
- the control unit can obtain the information from an ESP system and / or ABS system.
- the control unit can be configured to determine the information about the deceleration or deceleration values of the first wheel end based on the recuperated rotational energy.
- the speed can be determined from the recuperated rotational energy.
- the acceleration that is to say the deceleration
- the control unit can thus be configured to determine the deceleration of the first wheel end on the basis of the recuperated rotational energy. Accordingly, a sensor for measuring the recovered energy can be arranged at almost any location in a vehicle, since it does not have to be spatially provided directly on the recuperation device. Thereby, a degree of freedom in design can be increased. Furthermore, the sensor can be provided in protected positions, as a result of which the reliability of the sensor can be ensured and its service life can be extended.
- the control unit can have at least one sensor which is designed to determine the information.
- the sensor can, for example, be a speed sensor which is designed to measure the rotation of a wheel head or of the wheel heads.
- the speed can be determined by multiplying the rotational speed of a wheel end by the circumference of a running surface of a wheel mounted on the respective wheel end.
- the control unit can determine the acceleration (eg the deceleration) from the speed (ie from the change in speed) together with a time.
- the control unit can thus determine the deceleration of the first wheel head and / or of the second wheel head with the aid of a sensor which, for example, can measure the speed of at least one wheel head.
- two sensors can be provided which are each assigned to the first wheel head and the second wheel head.
- a central sensor can also be arranged, which can be an acceleration sensor and can be configured to measure the delays and / or a resulting torque directly.
- a first delay due to the deceleration of the first wheel head by the recuperation device can act, at another end of the axle on which the second wheel head is or can be arranged, A second deceleration can act due to the deceleration of the second wheel head by the braking device, and the control unit can also be designed to control the braking device and / or the recuperation device so that the first deceleration and the second deceleration are compensated or compensated for . are balanced.
- the deceleration can be a deceleration torque that can act on the respective wheel end.
- the end of the axle can be an axially outer end of the axle.
- the first delay and the second delay are expediently compensated if they are essentially the same size. In the present case, it can essentially mean that the second delay and the first delay are equal if they correspond to one another with a deviation of 5%. It can thus be ensured that a delay applied on one side or a moment resulting therefrom can be compensated (that is, compensated) by a targeted actuation of the braking device or the recuperation device.
- the at least one sensor can preferably be configured to determine a yaw moment of the axle and / or a speed of the first and / or the second wheel head.
- the sensor can be a sensor that is already installed in the car for other purposes (for example for an ESP system).
- the sensor can measure a yaw rate, for example with micromechanical rotation sensors, in particular based on silicon.
- the sensor is preferably arranged on or in the center of gravity of the vehicle on which the axis is seen.
- the speed can be measured with an ABS sensor already installed in a vehicle.
- the speed of the respective wheel end can be determined with the help of a pole wheel.
- separate and independent sensors can be provided for the above-mentioned applications.
- the measured values determined by the sensors can be made available to the control unit.
- the braking device can preferably be a mechanical brake, in particular a disc brake or drum brake. This allows Bremsvor devices to be used that are usually installed in vehicles, especially in commercial vehicles. It only has to be ensured that the braking device can be controlled individually by the control unit. In particular, the braking device can be controlled in such a way that the deceleration of the first wheel head due to the recuperation of rotational energy and the deceleration of the second wheel head can be coordinated with one another. The braking device can therefore be designed in such a way that the second wheel head can be decelerated individually and independently of the first wheel head by means of the braking device.
- the first wheel head can preferably be connected directly to the recuperation device, in particular without an intervening differential.
- the recuperation device can alswei sen a transmission and an electric machine.
- the electric machine can thus be connected to the first wheel head via the transmission.
- the recuperation device can be connected to the first wheel end by an axle shaft. Because the recuperation device is connected to only one wheel head (i.e. because the recuperation device is connected on one side), there is the advantage that there is no need for a differential, which means that less installation space is required around the axle. This makes the axle system more compact and less prone to damage. In addition, the weight of the axle is reduced.
- a trailer or utility vehicle trailer comprises at least one of the above axles.
- the trailer can for example comprise two of the above axes, both axes can be angeord net such that the first axis has the first wheel head on the left side of the trailer in the direction of travel and the second axis has the first wheel head on the right side of the in the direction of travel Has trailers.
- the control can be simplified, and the control unit can operate the recuperation device control that a deceleration on the first axis can be compensated for across axes with a deceleration on the second axis and vice versa.
- a deceleration of a wheel end due to recuperation on the first axle can thus be compensated for by a deceleration of a wheel end due to recuperation on the second axle.
- fewer braking interventions by the braking device are necessary, which can increase the efficiency during operation of the trailer.
- a method for compensating for a deceleration of a first wheel end of an axle, in particular for a utility vehicle such as a utility vehicle trailer, due to recuperation comprising the following steps: recuperation of rotational energy first wheel end, determining information about the deceleration of at least the first wheel end and compensating for the deceleration of the first wheel end by decelerating a second wheel end of the axle based on the determined deceleration of the first wheel end.

- the braking device 5 can effect a deceleration 9 on the second wheel head 3.
- the recuperation device 13 can generate a deceleration 8 on the first wheel end 2.
- a stabilization of the driving dynamics of the axle 1 can be achieved.
- a resulting moment 16 which rotates about the center point of axis 1, for example, is essentially zero.
- the resulting moment 16 is not equal to zero, but corresponds to an amount greater than zero.
- the vehicle on which the axle 1 is provided can become unstable in terms of driving dynamics.
- the driving dynamics instability can be used to improve cornering and / or maneuvering of a vehicle on which the axle 1 is installed.
